200 SEO factors you should consider

Google uses to determine which pages should be in the first results for what searches. If you apply all these elements of web positioning in your pages, you will have many options to be in the top positions of the SERPs .

Doman factors

  1. Domain age : Google takes into account the age of a domain at the time of positioning, but does not give much importance.
  2. Keyword in the domain : It does not have the impact of time, but having the keyword in the domain is still a sign of relevance.
  3. Keyword as the first word of the domain : A domain that starts with its target keyword, has an advantage over sites that do not use it or that place it in the center or end of its domain.
  4. Domain registration length : Valuable domains are paid in advance for several years, while the rest are rarely used for more than one year. Therefore, the date a domain expires can be used as a factor in predicting the legitimacy of a domain.
  5. Keyword in the subdomain name : If the keyword appears in the subdomain, you can boost the ranking.
  6. Domain History : A site with volatile property (via whois) can tell Google to “reset” the site’s history, denying the links that point to the domain.
  7. Exact match domain : It can be an advantage if the site is of quality. But if not, due to the latest updates from Google, it is vulnerable to penalty.
  8. Public vs. Private WhoIs: Private WhoIs information can be a sign that “there is something to hide”. Therefore, the best option is to keep it public.
  9. WhoIs Owner Penalized : If Google identifies a particular person as a spammer, it makes sense to investigate other sites owned by that person.
  10. Country TLD Extension : Having a Country Code Level Domain (.es, .fr, .it) helps site ranking for that particular country … but limits the site’s ability to position globally.

Page factors

    1. Keyword in the title tag : The title tag is the second most important part of the web page (in addition to the content of the page) and, therefore, sends a strong SEO signal on the page.
    2. The title tag begins with the keyword : Title tags that start with a keyword tend to have better results than the title tags with the keyword at the end of the tag.
    3. Keyword in the label description : Another sign of relevance. It’s not especially important, but it still makes a difference.
    4. The keyword appears on the H1 tag : The H1 tags are a “second title tag” that sends another signal of relevance to Google.
  1. The keyword is the most used in the content : That a keyword appears more than any other probably acts as a signal of relevance.
  2. Length of content : Google prefers extensive content to superficial articles. The length of the content is related to the search engine position.
  3. Keyword density : Although it is not as important anymore, Google uses keyword density to determine the theme of a web page.
  4. Keywords LSI : They are semantically related keywords. LSI keywords help search engines extract the true concept of words with more than one meaning. The presence of LSI also acts as a signal of content quality.
  5. Keywords LSI in title and description : As with the content of the web page, the LSI keywords in page meta tags help Google to discern between synonyms. It can also act as a signal of relevance.
  6. Speed ​​of loading pages through HTML : Google and Bing use the speed of loading pages as one of the 200 SEO factors of classification. Search engine spiders can estimate the speed of a site fairly accurately based on the code of the page and the size of the file. You can see the loading speed of your website with PageSpeed .
  7. Duplicate content : Identical content (even slightly modified) can negatively influence the visibility of a site. To check if Google sees your content as copied, you can use the Plagium tool .
  8. Rel = Canonical : When used correctly, the use of this tag may prevent Google from considering duplicate pages of content.
  9. Speed ​​of loading pages through Chrome : Google can also use Chrome’s user data to get better handling of the loading time of a page, since it takes into account the speed of the server, the use of CDN and other signals of site speed not related to HTML.
  10. Optimization of images : The images send a lot of information through its file name, alternative text, title, description and legend. So we must optimize images for SEO .
  11. Constant content updates: The latest update from Google favors recently updated content, especially for time-sensitive searches. To highlight the importance of this SEO factor, Google shows the date of the last update of a page.
  12. Magnitude of content updates : Adding or removing whole sections is a more meaningful update than changing a few words.
  13. Page Update History : The frequency of page updates over time also tells Google that the content of that website is refreshed periodically.
